Description: 8051单片机内部定时器的重叠使用。在某些情况下，两个定时器在程序中都投入使用，由于定时时间长（如1min以上或更长），使两个定时器定时出现重叠时间，即t0定时还未完成，t1也进入定时。如果在软件上处理不好两个定时器间的关系，程序就不可能正常执行下去。-8051 use an internal timer overlap. In some cases, the two timers in the proceedings are put into use, as from time to time a long time (for example, more than 1min or longer), so that the two overlapping time timer timing, that is, from time to time t0 has not yet been completed, t1 also entered from time to time. If the software can not be handled properly the relationship between the two timer, the program can not continue normal execution.

Description: 这是个机于8051单片机的超声波测距程序。工作原理为：
在发射端加一个8--15us的高电平，然后在接收端开始计时，此时接收端为高电平， 超声波在空气中传播一定时间返回接收器，接收端收到一个下降沿，这个过程就是超声波的传输时间，用下面的公式就可以测算出有形物体到测距模块的距离-This is a machine in 8051 ultrasonic ranging process. Working principle: the transmitter plus a 8- 15us' s high, and then start the timer at the receiving end, when the receiver is high, ultrasound propagation in the air some time to return the receiver, the receiver receives a falling, this process is the transmission time of ultrasound, using the following formula can measure the physical distance from the object to the distance measuring module

Description: 一、设计要求：交通信号灯模拟控制系统设计利用单片机的定时器定时，令十字路口的红绿灯交替点亮和熄灭，并且用LED数码管显示时间。用8051做输出口，控制十二个发光二极管燃灭，模拟交通灯管理。
二、设计内容：因为本课程设计是交通灯的控制设计，所以要了解实际交通灯的变化情况和规律。假设一个十字路口为东西南北走向。初始状态0为东西红灯，南北红灯。然后转状态1东西红灯，南北绿灯通车，。过一段时间转状态2南北绿灯灭，黄灯亮5秒，东西仍然红灯。再转状态3，东西绿灯通车，南北红灯。过一段时间转状态4，东西绿灯灭，黄灯亮5秒，南北仍然红灯。最后循环至状态1。
注意：.双色LED是由一个红色LED管芯和一个绿色LED管芯封装在一起，公用负端。当红色正端加高电平，绿色正端加低电平时，红灯亮；红色正端加低电平，绿色正端加高电平时，绿灯亮；两端都加高电平时，黄灯亮。-First, the design requirements: traffic light control system using single chip analog timer timing, so that the traffic light intersection
Alternating light and off, and LED digital display with time. To do with the 8051 output, control, burning off a dozen light-emitting diodes,
Simulated traffic light management.
Second, the design of content: This course is designed for the control of traffic light design, so to understand the actual changes in traffic lights and rules
Law. Assuming a crossroads for the north-south thing. What the initial state 0 is red, north and south light. Then things turn state 1
Red, green north-south traffic. Over time, turn off State 2 South Green, yellow light for 5 seconds, things are still red. Sub-state
State 3, the opening of something green, north and south light. Switch to state 4 over time, things off the green, yellow light for 5 seconds, north and south are still red
Lights. The last cycle to the state 1.
Note:. Two-color LED is a red LED
